SQL Server Hosting
SQL (Structured Query Language) is a database computer language designed for the retrieval and management of data in relational database management
systems (RDBMS), database schema creation and modification, and database object access control management.
SQL is a standard interactive and programming language for querying and modifying data and managing databases. Although SQL is both an ANSI and an ISO
standard, many database products support SQL with proprietary extensions to the standard language. The core of SQL is formed by a command language
that allows you to retrieve, insert, update, and delete data, and perform management and administrative functions.
The SQL language is sub-divided into several language elements, including:
- Statements which may have a persistent effect on schemas and data, or which may control transactions, program flow, connections, sessions, or
diagnostics.
- Queries which retrieve data based on specific criteria.
- Expressions which can produce either scalar values or tables consisting of columns and rows of data.
- Predicates which specify conditions that can be evaluated to SQL three-valued logic (3VL) Boolean truth values and which
are used to limit the effects of statements and queries, or to change program flow.
- Clauses which are (in some cases optional) constituent components of statements and queries.
A variety of databases which support basic SQL (or an extended version) are available, such as: MySQL, PostgreSQL, MS SQL,
and Oracle. Conexim provides hosting services for all those different databases.
